SVN rev 195693 on 2009-07-14 19:45:36Z by jhb
- Change mmap() to fail requests with EINVAL that pass a length of 0. This
behavior is mandated by POSIX.
- Do not fail requests that pass a length greater than SSIZE_MAX
(such as > 2GB on 32-bit platforms). The 'len' parameter is actually
an unsigned 'size_t' so negative values don't really make sense.
